Thanks misschief - that is very apt.
An idea did occur to me while I was cleaning - it made me giggle (I might still do it), but ...
I have already come to the conclusion that a soap with soap dough blowfly's on it wouldn't be particularly popular
(we are coming into Summer, and December is always blow-fly's and BBQ's, with a little beach thrown in for good measure)
... perhaps it would be better I wait a little more yet
I woke up on Sunday (after a Saturday filled with making) with a full blown idea for my soap. I know EXACTLY what I'm going to do. Now, I just need the time to do it.
